Downvoted for wrong solution. A river is carrying water containing 2000 mg/l Magnesium Chloride into a small lake. The lake has a naturally occurring Magnesium Chloride of 50 mg/l. If the river flow is 2500 Lmin and the lake flow rate is 1.5 m³.sec¹, what is the concentration of MgCl2 in the lake after the discharge point? Assume that the flows in the river and lake are completely mixed, that the salt is a conservative substance, and the system is at steady state.
Initially, a tank is filled with 100 liters of pure water. Brine carrying six grams of salt per liter enters at a rate of four liters per minute. At the same rate, a well-mixed solution emerges from the tank. After how many minutes, the tank's concentration will be 3 g/L?
An aqueous waste stream that has a maximum concentrationof 0.50 M H₂SO₄ (d=1.030 g/mL at 25C) will be neutralized by controlled addition of 40% caustic soda (NaOH; d=1.430 g/L) before it goes to the process sewer and then to the chemical plant waste treatment facility. However, a safety re-view finds that the waste stream could meet a small stream of animmiscible organic compound, which could form a flammable vapor in air at 40.°C. The maximum temperature of the causticsoda and the waste stream is 31°C. Could the temperature in-crease due to the heat of neutralization cause the vapor to ex-plode? Assume the specific heat capacity of each solution is 4.184 J/gK.
A sample may contain any combination of sodium hydroxide, sodium carbonate and sodium bicarbonate with inert matter. A 3.00g sample requires 57.57ml of 0.5N hydrochloric acid to reach phenolphthalein endpoint and a total of 105.4ml of acid was used until the methyl orange endpoint was reached. What is the percentage inerts in the mixture? What is the percentage sodium bicarbonate in the mixture? What is the percentage sodium hydroxide in the mixture? What is the percentage sodium carbonate in the mixture?
A brine solution of salt flows at a constant rate of 4 L/min into a large tank that initially held 5 L of pure water. The solution inside the tank is kept well stirred and flows out of the tank at a rate of 2 L/min. If the concentration of salt in the brine entering the tank is 0.1 kg/L, determine (a) the mass and (b) the concentration of salt in the tank after 30 mins.
An experiment was conducted to determine the effect of glucose on the freezing point of water. Experimental data showed thatthe freezing point depression of water in solution was –2.6°C when 1.0 g of glucose was dissolved in 10g of solvent.
